Review: Powerful Ventilation Solution for Mining Room – Quiet and Efficient - The AC Infinity CLOUDLINE S8 PRO has been a total game changer for venting my miner room. The 8” inline duct fan moves a huge amount of air while still being surprisingly quiet thanks to the EC motor. The 10-speed controller makes it easy to fine-tune airflow depending on the temperature load, and I’ve noticed a big difference in keeping my miners cool and stable. Build quality is excellent — sturdy housing, smooth fan operation, and the controller feels responsive and reliable. Installation was straightforward with the included hardware, and once running, it just works flawlessly. ✅ Pros: Moves a lot of air with quiet operation 10-speed controller allows for precise airflow control Solid build quality, built to last EC motor is energy-efficient and quiet Perfect for grow tents, server rooms, or mining setups ❌ Cons: Higher price point than basic fans (but worth it for performance and reliability) Ducting not included, so you’ll need to purchase separately 💡 Tips: Pair it with insulated ducting to reduce noise further. Position exhaust outside or into a larger ventilated area to prevent recirculating hot air. Use a temperature/humidity controller with it for fully automated cooling. Mount with rubber isolators if possible to cut down on vibration. Bottom Line: This fan is a must-have for serious ventilation needs. If you’re running miners, servers, or even grow tents, the S8 PRO is a reliable, efficient, and quiet way to keep heat under control. Well worth the investment.
Review: Great fan, can be dangerous though - The fan works great and has a wide range of performance that allows you to run this thing at any speed between silent and very loud. I use mine as part of a DIY ventilation system for an old apartment and it provides loads of air movement and static pressure. At full blast, I measured its power draw at 165 watts. The fan is notably very efficient and can still move a surprising amount of air at its lowest speeds with around just 5-10 watts of power usage. (Though you won't be ventilating a whole space at that level.) One thing to seriously note though: This fan can be a real safety hazard if not used correctly. It should really have some feature to kill the power easier since at full blast this fan will happily consume any nearby debris and probably result in injury if you were to get your hand in it. There is no built in grill or safety screen. The controller allows for the selection of 10 speeds, but requires you to loop through to the highest speed before it will shut off. Additionally, when you remove the controller by disconnection, the fan defaults to FULL power. I had an incident where the fan swallowed a bag of small screws and I had to hastily chase down the power plug in order to shut it off. I guess as a testament to its durability though the fan didn't seem to suffer any damage. I have since included a shutoff switch in-line with the power cord.

## Questions & Answers

**Q: We purchased the fan it is only 2 months old.  Why does it turn off constantly even as the light remains on?**
A: Might be defective or you have it on the wrong settings. Try unplugging it and if it continues to to the same then it might be defective

**Q: Can this fan be used as an inline blower for ventilating a blowerless kitchen range hood? i.e. is it rated for exhausting steam and grease?**
A: I would have to say no for grease but yes it will work to vent steam even though it is not rated for this I have used them in my bathroom for over a year now and have not had any issue.

**Q: What happens if power goes out? Does it kick back on to same speed settings? How long would it hold thise settings with power out?**
A: If power is removed the fan will restart at same speed as operating before powered off. As far as how long will it retain speed setting, not sure but at least three weeks.

**Q: Would this be used in a cigar room in conjunction with a air purifier? Looking to build a cigar lounge in my house.**
A: i think so - i used it to improve air circulation in a 3 story house. i think it would work well for your purpose. it is quiet and has adjustable flow rate.

### ⭐⭐⭐⭐⭐ Great inline style fan , would definitely recommend
*by H***W on April 21, 2026*

This fan is seriously solid. The AC Infinity CLOUDLINE S8 PRO is super quiet for how powerful it is, and the airflow is no joke—it moves a lot of air without sounding like a jet engine. The 10-speed controller is easy to dial in, and it’s nice having that fine control. Build quality feels premium and it just runs smooth and reliable. Definitely overkill for small setups, but perfect if you need strong, efficient ventilation that you can trust long-term.
